Deanna and Kelly were lifting weights. Kelly was easily doing the exercise and she didn't feel like the exercise was very intense. Deanna suggested she increase the weight stack amount by 50 percent. Kelly was using 8 pounds initially. What amount should she use based on Deanna's suggestion? (2 points)

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
